Development and psychometric validation of the Sickness Presenteeism Scale‐Nurse.

Aim: This study's aim is to develop and psychometrically assess the Sickness Presenteeism Scale‐Nurse. Background: Evaluation of the effects of sickness presenteeism on nurses' performance and productivity is important for healthcare quality. Design: This was an instrument development and validation study. Methods: Scale items were created based on literature review and qualitative research. Data were collected from 619 nurses between October and December 2021. The factor structure of the scale was determined by explanatory and confirmatory factor analysis performed with different sample groups. Convergent and discriminant validity were investigated, and reliability was evaluated with Cronbach's α values, adjusted item‐total correlation, composite‐reliability and split‐half reliability. Results: Explanatory factor analysis showed that Sickness Presenteeism Scale‐Nurse consisted of four sub‐dimensions and 21 items and explained 57.9% of the total variance. This factor structure was confirmed by confirmatory factor analysis. The convergent and discriminant validity was confirmed. The total Cronbach's α value of the scale was calculated as 0.928, with Cronbach's α values of the sub‐dimensions calculated as 0.815–0.903; composite reliability values were calculated as 0.804–0.903. Conclusions: The Sickness Presenteeism Scale‐Nurse is a valid and reliable measurement instrument that can be used to evaluate the effect of nurses' sickness presenteeism behaviour on job performance. Summary statement: What is already known about this topic? Presenteeism can reduce work performance and productivity.Nursing is one of the occupations where presenteeism is commonly reported, but there is no scale to measure the effect of presenteeism on nurses' work performanceWhat this paper adds? In this study, the Sickness Presenteeism Scale‐Nurse, an instrument that can be used to evaluate the effects of sickness presenteeism on nurses' work performance, was developed.The Sickness Presenteeism Scale‐Nurse consists of four dimensions: general performance, patient safety, relationships within the team and emotion.This study provides evidence of the validity and reliability of the Sickness Presenteeism Scale‐Nurse.The implications of this paper: Effects of presenteeism on the performance and productivity of nurses can be evaluated by using Sickness Presenteeism Scale‐Nurse to provide information to guide policy makers in determining interventions to promote work performance and productivity.
